Witnesses inn sin ne r MATTHEW To all whom it 722 ,1 concern:

Be it known that l. MATTHEW W. Pnr'ron, a citizen of the United States,residing at Newberg. in the county of Yamhill and State of Uregon haveinvented a new and useful Tractor, specification.

The present invention relates to improvements in tractors, the primaryobject of the invention being the provision of av tractor provided withtwo rear tractor Wheels and a single steering tractor at the forward endthereof, the rear tractors being provided with an individual motor Whilethe forward tractor is provided With its individual motor, thusproviding a means whereby the full draw bar or traction effect isimparted throughout the full length of the tractor, and further a meanswhereby the forward end of the tractor may be turned at right angles insteering Without the danger of skidding, where the forward wheels aremerely steering Wheels.

A further object of the present invention is the novel form of tractorhaving rear tractor wheels driven by a single motor in combination witha turn table disposed at the front end of the frame of the tractor andcarrying a single tractor and its operating motor, such arrangementdistributing the tractor or drawing; power at both ends of the frame ofthe tractor and giving the maximum pulling power to a machine of thischaracter, whereby the power necessary to push the ordinary steeringWheels isv dispensed with, every unit of power being employed to thebest advantage'both in agricultural and in road ork.

\Vith the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement ofparts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed Without departing from the spirit of theinvention.

In the drawingsi*igure l is a top plan view of a complete tractor madeaccording to and embodying the present invention. Fig; is a sideelevation thereof, a section being taken through the forward part of theframe and turn table to show the mechanism carried by and the mountingof'the turn table.

.ieferring to the drawings, the numeral 1 designates the main frame ofthe tractor carrying" the rear axle 2 upon which are keyed the two reartractor Wheels 3 which are disposed as is usual, the explosive engins 4for driving the rear tractors being mounted upon the frame with thegreatest portion of the weight above the rear axle. The crank shaft ofthe engine carries upon one end a large gear:- 5 which operates theintermediate gear 6 carrying the small gear 7 which in turn meshes with.and operates the large gear 8 keyed upon one of the tractor wheels 3 asclearly shown in Fig. 1. By this means the operation of the engine 4;will impart rotation to the rear tractor Wheels 3.

The crank shaft of the engine 4% is provided upon one side with the flywheel 9 and upon the other side with the drive pulley 10, the purpose ofwhich will later appear.

Carried by the front part of the frame 1 is a metal ring 11 having theenlarged portion 11 connected to the frame 1 and constituting theforward open portion of the and also upon the upper surrace of the enlarged portion 11. in order to reduce the friction between the turntable and the open ring 11. the anti-frictional bearings 14' areemployed.

lonnected to the under side and carried by the turn table are the frames15 which have journaled therein the axle 15' carrying the forward.tractor wheel 16 said tractor wheellG being" disposed in thelongitudinal center of the main frame of the machine as clearly shown inFig. 1.

'Mounted upon the turn table 13 is an explosive engine 17 which operatesthe crank 18 and the fly or balance Wheel 19, and through the clutch 20transmits motion to the gear 21, which in turn meshes with the gear 22mounted upon the counter shaft 23 carrying the small gear 26*. The gear2% meshes with the intermediate gear :25 also carried by the turn. tableand through the gear 25 transmits motion to the gear 26 carried by thetractor Wheel 16. Thus the operation of the motor or engine 17 willcontrol the rotation of the tractor wheel 16 and with the tractor wheels3 provides independently propelled tractor means at the respective frontand rear ends of the machine.

Mounted upon the crank shaft 18, upon the same side as the fly wheel 10,is the drive wheel 27, which is connected to the drive wheel 10 througha belt 28, thus providing a means whereby the two engines 4 and 17 maybe coupled for simultaneous operation when it is desired to operate themotors or engines for driving threshing machines or other like machinerywhen the tractor is in a stationary position. Either fly wheel 9 or 19is then employed to attach the belt for operating the machinery, or thebelt 28 may be thrown and the two motors or engines operated separatelyto drive two dilferent mechanisms.

In order to operate the clutch 20 to throw the forward tractor operatingmechanism into or out of operable relation to the motor or engine 17, abell crank lever 29 is situated in the. frame carried by the turn table13' and is itself connected to the small bell crank lever 30, which iscontrolled by means of the links 31 and the long connecting rod 82 whichextends to the rear of the machine and is provided with the operatinghandle 33, so that the clutch may be controlled by a person standing atthe rear and operating the machine.

In order to oscillate, the turn table and consequently the forwardtractor 16, to steer the tractor, the chain 34 is connected to the drumformed by the lower portion of the ring 13 at diametrically oppositepoints thereof and extends rearwardly around the sprocket 35 mounted inthe frame 36 and carrying the worm 37 which is operably connected to theshort shaftBS, which through the flexible connection 39 is connected ,tothe operating shaft 40 which extends rearwardly and carries the steeringwheel ll-which is laced in suchposition that both it and the liver 33may be operated by the person for controlling the direction and speed ofthe machine.

From the foregoim description taken in connection with the rawings, itis evident that with a tractor constructed according to the presentinvention, the skidding of either set of wheels is prevented, and byreason of the fact that the tractor 16 is carried by a turn table whichis capable of being ro tated a full 90 in either direction the tractorwill turn in the shortest possible space, approximately the full lengthof the machine with the rear tractors as the center, and further thatthe tractor power being imparted to the surface at both ends oftheframe, the liability of skidding is reduced to a minimum while thetraction power of the machine is increased.

By reason of the fact that the forward tractor 16 is provided with itsindividual motor and further is not pushed or propelled by the reartractor wheels as is the usual case, the full engine power maybeemployed entirely for traction purposes and not for propelling deadweight as is the case where the forward wheel is simply a steeringwheel.

Although, there are shown rear traction wheels, it is evident that abaling press mechanism may be attached in lieu of the traction wheels 3,and'thus Provide a portable traction baling press, with the front wheelthe load puller.

\Vhat is claimed is:

A steering tractor including a member r'or attachment to a frame, saidmembers having a circular opening, a ring mounted for rotation withinthe opening and having an enlarged lower portion extending under saidmember and forming a drum, a tractor wheel under and connected to thering, the upper portion of the wheel projecting upwardly into the ring,a table secured upon the ring and extending over a portion of thestructure, a motor mounted upon the table, means mounted on the tableand within the ring for transmitting motion from said mo- MATTHEW \V.PATTON.
